Description
- Rhenium cube using high-purity rhenium plate Re9999 as raw material, artificial fine grinding and polishing, very smooth, basically reached the mirror surface, the effect is very good, is a very delicate collection, the average weight of each about 20-20.5g or so, the side of the length of 10mm * 10mm * 10mm, high-power high-precision laser marking, the text is concave, non-human corrosion or abrasion, the text will not disappear.
- Rhenium is an extremely rare and uncommon metal, one of the least abundant elements in the earth's crust, with an average content of one part per billion, and the last stable element to be discovered.
- Global rhenium production of 70% are used in aerospace engines, high temperature alloy components, but also used in the manufacture of platinum - rhenium catalysts, tungsten - rhenium alloy.
- Rhenium is very stable at high temperatures, has low vapor pressure, is resistant to abrasion, and is able to resist arc corrosion, so it is a good material for self-cleaning electrical contacts.
- Gold is now the world's annual production of more than 2,000 tons, while the world annual production of rhenium metal is only 40 to 60 tons, rhenium's melting point is second only to tungsten in all metals, up to 3180 ℃. The relative density of dense rhenium reaches 21.02, which is the fourth highest among the metal elements.
